AlphaCrypt - this looks heavily based on TeslaCrypt (based on some quick static analysis anyways)

I originally found a post about it here http://www.malware-traffic-analysis.net ... index.html

Attaching the sample for convenience

Tried the new sample in a VM and can confirm, it looks exactly like TelsaCrypt. Thanks for posting the sample :)

There is a new variant outside. It encrypts the files adding a ".vvv" extension. Somebody has the MD5 or the sample to share?

Thanks in advance
